commit 97291741 upstream.

Since commit 9bcf15f7 ("iio: adc: axp288: Fix TS-pin handling") we
preserve the bias current set by the firmware at boot.  This fixes issues
we were seeing on various models, but it seems our old hardcoded 80ųA bias
current was working around a firmware bug on at least one model laptop.

In order to both have our cake and eat it, this commit adds a dmi based
list of models where we need to override the firmware set bias current and
adds the one model we now know needs this to it: The Lenovo Ideapad 100S
(11 inch version).
